Introduction: The Road from the Austrian Alps to the Venetian Lagoon
The drive from Klagenfurt to Chioggia covers 340 kilometers, starting at the Wörthersee and ending on the shores of the Adriatic. The route crosses the Karawanken mountain range via the Karawanken Tunnel (A11/E61), then descends through Slovenia and Italy to the Venetian lagoon. This road trip offers a stark contrast: from alpine lakes and dense forests to the flat, agriculture-rich plains of the Veneto region. The Karawanken Tunnel, completed in 1991, is a key milestone at 7,864 meters long, saving time but requiring a toll of €7.50 for passenger cars.
